Joshua Kinard a2e50f53d5 MIPS: PCI: Add a hook for IORESOURCE_BUS in pci_controller/bridge_controller ... On SGI Origin 2k/Onyx2 and SGI Octane systems, there can exist multiple PCI buses attached to the Xtalk bus. The current code will stop counting PCI buses after it finds the first one. If one installs the optional PCI cardcage ("shoebox") into these systems, because of the order of the Xtalk widgets, the current PCI code will find the cardcage first, and fail to detect the BaseIO PCI devices, which are on a higher Xtalk widget ID. This patch adds the hooks needed for resolving this issue in the IP27 PCI code (in a later patch). Verified on both an SGI Onyx2 and an SGI Octane.
